Page 4: Module Overview
Model 4500 MPEG Stream Processor MODULE OVERVIEW DVB-ASI and SMPTE 310M Converter and MPEG Transport Processor The 4500 MPEG Transport Stream Processor processes DVB-ASI and SMPTE 310M bitstreams. It provides stream content analysis with support for Priority 1 and Priority 2 test protocols of the ETR 290 DVB measurement guidelines. -
Page 5: Clock Quality And Transmission
Model 4500 MPEG Stream Processor Clock Quality and Transmission This section addresses the underlying capabilities of the 4500. As background for that discussion, we will take a quick look at the components of the transport stream. The Transport Stream Hierarchy The transport stream works as a hierarchy. -

However, these computer grade clocks are not su cient for creating a waveform as complex as 8 VSB modulation. Placing an Avenue 4500 MPEG Stream Processor in front of the ATSC Exciter helps the transmitter present the cleanest possible digital signal. -

In contrast, the Avenue 4500 overcomes underlying frequency error by separating the content from the original clock and generating a new output based upon more accurate and more stable clocks. - Page 8 Model 4500 MPEG Stream Processor As a transport stream arrives at the input of the Avenue 4500, the signal is deserialized and the Data packets are saved into a bu er. The Null packets are discarded. Guided by a reference clock, Data packets are read from the bu er. Null packets are inserted as needed to bring the total bit rate up to 19.39 Mb/s.
